Rating - Horizontal Multipass Flow TEMA BEM Shell With Single-Segmental BafflesUnit ID 100 - WARNING MESSAGES (CALCULATIONS CONTINUE)

The maximum process temperature is outside the correlational range of the automatic tube materialdata bank. The tube metal properties were calculated at the temperature limit. For tube metalnumber 1 the temperature limit is 21.11 C. Temperature limits are available in the HTRI XchangerSuite online help file.

The estimated tube count for this shell is 30. A large variation from the expected tube count mayindicate that program has used different clearances (such as bundle-to-shell clearance andheights-under-nozzles) than those expected. Although the specified number of tubes has beenused to calculate the available heat transfer area, discrepancies in exchanger clearances can resultin inaccurate pressure drop and heat transfer calculations.

An internal temperature cross exists in the exchanger. The program handles the reverse heat flowproperly in the calculations, but you may want to consider changing the terminal process conditionsto avoid the internal temperature cross.
